Rack don't find GLEW

[3fla1416]

Hi,

Rack don't find GLEW on my laptop.
My graphique card is "VGA compatible controller: Intel Corporation Raptor Lake-P [Iris Xe Graphics] (rev 04)" with latest intel driver.
And under Wayland.
So i don't think that don't work with openGL.
But when i start Rack, that said :

pierre@fedora:~$ Rack2
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:802: FINISHME: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:834: FINISHME: support more multi-planar formats with DRM modifiers
terminate called after throwing an instance of 'rack::Exception'
what(): Could not initialize GLEW
Abandon (core dumped)

And a prompt message :

Could not initialize GLEW. Does your graphics card support OpenGL 2.0 or greater? If so, make sure you have the latest graphics drivers installed.

So i compile rack by myself and that work ( without static stdc++).

In spec file, a lot of compile libraries are remove and the GLEW library.
I think Rack don't find the fedora GLEW library and start with it.

I don't know if this is specific with my graphic card or not. I can't check with other graphic card.

Somebody can reproduce this ?

I will try to check if I can reproduce the problem ASAP.

I can reproduce this issue with a "Mesa Intel(R) UHD Graphics 620 (KBL GT2)" graphics card/driver on Fedora 42. On Fedora 41 everything worked as far as i can recall.

Just tested again and it doesn't work anymore.
I just switched to Fedora 42 ...
Cardinal works ... As a temporary work around ...

[ycollet]

I will try to build rack with a static version of GLEW ...

[ycollet]

Tested various things and ... I finally started Rack as a root user. It started.
So, maybe a permission problem.
I disabled SELinux to check and Rack didn't start.
I checked some groups I found in Fedora, no improvement yet.
I will ask on Fedora Discussion ...

Found an archlinux thread with this problem:
https://bbs.archlinux.org/viewtopic.php?id=299546

Tried on my side and didn't work here.

I was able to switch from intel to nvidia but the problem is still here:

$ Rack
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:802: FINISHME: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:834: FINISHME: support more multi-planar formats with DRM modifiers

The build with a static glfw from Rack works.
I will start this build tonight.

[ycollet]

I add here a new link to an old GL driver removed which can produce this kind of error.
https://bbs.archlinux.org/viewtopic.php?id=304480

I build is done in the COPR repo. Hopefully fixing this problem.

[ycollet]

Seems to work now. Can you test on your side ?

[3fla1416]

Yes it's work.

I think it's temporary until the trouble with glew lib are fix.

A priori, it looks like the problem was related to glfw. I used the one shipped by VCVRack and glfw is linked statically to VCVRack.
